To all whom it may concern.'

` VBe it known that I. linxaa MiN W. Trinizu, a citizen` of thel'nited States, and a/-resident of South Orange. county of Essex, and State of .\`ew Jersey. ha re. invented certain new and useful Improvements in Type- Writingr l\Iacliiiies of which the following is alfull, clear, aml exact description.

This ii'ivention relates more particularly to a front strike or other visible writingr iliaehine wherein one part ot the machine is movable relatively to another part to make the machine compact when not in ilse and to adapt the same for convenient transportation and other purposes.

Une of the principal objects of the invention is to provide a collapsible t. vpe. writing machine. having a iiian frame part. adapted to support the t \,'pe-vbar action in eludingfthe typte-bars and the hey-operated lcvcrh` thlfrefor, aud another relatively and horizontally movable frame nai-t ou which is mounted tihe platen andcatriage and the associated parte` usually coipeiiitug with the platen. and so to construct said frame parts that one of the frame. parts may be moved 'from a normal operative position to a more compact one.V l

Another object ofjthe. invention is to provide a simple andfet-iicient horizontally collapsible writing'inii'ihine in which there is a com ilete break between the associated parts or the platen carriage including the universal har aml the tlvpe action.

Uther objects of the. invention are to provide simple and etlicient means for holding the frame parts of the machine vand foi-locking the. same in a normal position or in an abnormal inoperative. position; to provide simple means whereby the universal bar is adapted to be moved to a compact position with the platen carriage ai'idvin the normal operative, yposition of the said bar adapted to be, engaged by and moved during Athe printing nioven'ient of the type-bars; and to provide simple means wherebva carriage and the associated parts including the,l universal bar mavlbe suitably mounted upon a horizontally Slidably held frame part of the main machine-frame. i

A further object of the. invention is to provide a situ-ple and ecient machine wherein the frame parte are adapted to have a compact. movement and said frame parts so con- 4strut-ted that either a type. segment orphten` case shift may be employed.

A still further objectl of the inventionvis; to provide a machine wherein the nrts `may ile-readily constructed and aseemb ed.`

n With these and other objects in view,`the invention will be hereinafter more particle'.v

larly described with reference to the aceonipanyingdrawings, which form a part of this application, and will then ibe ointed out in the claiinsat the, end of the esci-iption.

. ticular kind of typewriting machine, it; will `be undeistood thatthe invention andinany of the features shown and describdjmay bel employed -in connection with-.various kinds'.4 illl( In Figs. 1 .to 4 the 'invention is 'shown as applied to a machine wherein the type-bars operate the imiversal beraad-wherein the type-hars are shifted for case'gshifbpub posee. As shown the main frame 10 com )rises a main frame part 11, forming the ase for the machine anda 'relatively movable frame party 12. zI`he base o r'frnme 11l comprises` side laieslwhich may be connected 'at their renti portions by a traag verSely substantially L-shapedpbar 14,- imd said base on frame part may be provided llill -pairs by a. link versely extending with means ,for holding the usual rubber feet or tips 15 to. support t e machine. A transversely extendm bar 16 extends between the sides 13,*an pivotall' held in slots 17 in said transversely extent ing bar are levers `ferent directions so as to provide a plurality of banks or' groups, the keys 22 of the dit'' ferent banks being at diil'crent elevations as is usual in the keyboards of typewriting machines. Each key-lever 21 has its cooperating pair of levers 18 and 19 and said levers atthe inner ends are connected in 23. A rod or link 24 ronnects each link and pair of levers 1S and 19 to an arm 24 of a type-bar 25, there being a spring 25 tending normally to hold each key-lever in its normal position. The type-bars are pivoted at 26 to a vertically movable segment Q7 at their rear ends and at their forward ends are provided ywith a plurality of type' 28 varying in number according to whether a single or double case -shift is employed. If a single case shifty is employed each type-bar carries two tyiies or characters and iff a dou'ble case shift is employed three type characters are arranged at the forward end of each type-bar. As the keys422 are depressed, the levers 1S andv19 will be moved'on their pivots and through the links 28 and 24- will move the type bars on their pivots to force the type thereon upwardly and rearwardly to make an impression on the work sheet, about a platen 29 the latter being mounted on a carriage 30 which is adapted to travel transversely of the machineon'the main frame part 12.

The main frame part 12 may comprise side plates or members 31 which may be connected at their rear portions by ay transbar 32.v r`his bar' is adaptedgto form a bed for the carriage 30 alon which bed said carriage -is adapted to trave -Theframe part-12 hasits side plates 31 held to slide horizontally on OHV-set portions 33 of the side plates 13 of the'main base member 11. The off-set' portions 33, each have a substantially horizontal straight part 84 on which rests the straight lower edge 35 of the frame side plates 31, and each of 'thevframe side plates 31 bears againstand is adapted to slide along a vertically-- extending part 36 of lthe base side plates In each art 36 is a' horizontally extending slot 37,v ig. 3, throughwhich is adapted to extend the shank 'or stem ofa screw 38.

Each screw has a milled head 39 bywhich the same boI easily rotated and at its inner end each screw is adapted to engage a threaded o )eninpr in one of the sides 251 of the main irame part 12. each have a clamping collar or shoulder 40, and when the said screws are released the frame part or member 12 with the parts mounted thereon may be forced forwardly from the position shown in Fig. 2, to that shown in Fig, 3 or vice versa, and by tightening ie screws the frame parts may be held in such adjusted positions. In the position show'n in Fig. 4, the parts are in their normal operative position while in Fig. 3 the frame parts have been moved so .that the machine is materially shortened from front to rear making the machine more compact and convenient for transportation purposes.

As a case shift various means maybe eml ployed. As shown the type-bar segment 27 is held to a frame 41 and this frame is mounted upon parallel arms 42 and 43. The arms 43 are pivotally held to the frame sides 13 while. the arms 42 are held to a transversely extending shaft 44. One of the arms 42 forms a part of a hell-crank lever 45, the upwardly extending arm lli of )vhic-h is provided with a roll 17. The roll 47 extcndslinto slots 4S and 49 ofshift levers 50 and 51 respectively.v The slots 48 and 49 extend in opposite directions so that when one shift lever is depressedit will move the segment 27 and frame 41 vertically in one direction, and when the other lever is l 48 thereof will cause the roll 47 to bemoved inwardly and this will force the segment27 downwardly, while if the shift lever 51 is depressed the roll 47 will be forced forwardly and this will elevate the arms 42 thereby elevating the segment 27. und the 'frame 41 on which the segment is mounted. j

This frame 41 has forwarr y extending arms to which the type basket 54 is held so that said type basket, typ`e-bars and type segment may all move together vertically as the shift levers 50 and 51 are depressed. T he slots 48 and 49of the shift levers intersect.

and are so arranged that they substantially lock the roll 47 in its normal position until one of the shift levers is operated.. .The shift levers may be restored to their normal position by means of springs 55 and the type basket. and segment may be counterbalaneed or assisted in being held in its normal posi- Imo tion by means ot one ci' more springs 56.

`The arrangement and construction of the type action and' shift mechanism is not new with flapplicant and is not specificallyI claimed herein,

The `platen carriage and the associated parts lfor themost part are substantially the same as einhodiedin the Corona typewriter., Ae shown the platen 29 is mounted to rotate at .its ends in the carriage 30 and is provided at oneend with a knob 57 and at its other end with suitable line-spacing mechanism by which the platen may be rotated in the usual way. The paper apron 58 has' a pressure roll`59 and a scale 60 mounted tl'iereon,` and movable. with the carriage. are paper fingers "'61 which'are adjustable lengthwise of the platen.` .'lhe carriage base 62 may have rolls 63 and au track 64 under which are `suitable anti-friction devices, as balls, by which the carriay'ge may move easily along the bed 32 underthej tension of the usual spring drum inlthe usual wa A universal bar 65 is mounted to reciprocate horizontally under the carriage bed-32. This universal bar extends transversely `of the machine between the side plates 31 'of' the main frame part 12 and said liar has a downwardly .extendin flange 65* which is adapted to be engage by a part 66 on each of the type-bars 25. The universal bar at its ends has angular 'parts 67 provided with lugs to which are pivQted the upper ends of arms 68. These arms 68 are pivoted at 69 at their lower ends to-the side plate 3l `and are adapted to support the universal bar so as to move horizontally when actuated' by any one of the type-bars. The universal bar may be provided with a tappet' as 70, Fig. 1, which tappet is adapted to engage a part71 extending inwardly from a dog,r carrier forming a part of an escapemeiit mechanism.

lThe escap'ement mechanism and do M carrier is not shown 'in detail bi1t is su stan* tially the same and# is operated in the saine way as` in the Corona typewritin machine.

Itwill be .evident that when t e keys 22 are depressed'to operate the type-bars for println purposes'tlie type-bars diirng their upwarcly and-rearward movement will engage and move the universal ba'r and such mechanism.

movement of the universal bar will move ,the escapeinent dogs` thereby permitting the carriage "to move a letter space under the control of the spring drum o'r otherl tension The'iiniversal bar may serve as` a means y on which may bel mountedia part of the iiiecliaiiism for feeding the gibhon leiigthwiseas well as the ineanswhereby the rib-y Ibon may be .vibrated to cover and uncoverl the"printiriig` oint; The si'iecifie `construction of such eatures are neither shown in detail nor are they claimed specifically in this` application and have Aa bearing' in this application-only so far as their mounting and arrangement in relation `to other parts of the machine are concerned. .'l`lic'uuiversal bar for the ribbon lengthwise feed nicchanisin carries a pawl 7:2 on eachsidc thereof `and each pawl is adapted-to engage a toothed wheel .73. The toothed vheel73 carries-a worm 73'* andI this worm is adapted to `eii gage a worm wheel 74 on the shaft ot cach of the spools 75. The spools 75 arefto be held'to rotate with a shaft by means of a nut 76 as in the Corona typewriter sov that i on releasin one nut and tightening :the other the r1 bon may be fed to either side of the machine with" a step-by-step movement,

Such inoveiiient'heing effected by the engagement of' theipawls 72 with the wheels 73 during the reciprocatory.back and forth movements of the universal bar'at each printing opera tion.

The universal bar by the space bar 77 which may be operatively connected to a spacing'lever, not sliown,in substantially the saine manner as the connection is made between the keyoperated levers andthe type-bars, a spring 77 being provided torestore the Sp`:ic(-.liiir to its normal position. The-spacii'ig lever for operating the universal bar without printing may be exactly the same 'as the' type-bar only of less l'engthand,may-nor# mally lie in close relation to one of" the typebars so thatoii the depression of. the' space bar rthe spacing lever will be l'oi'ced upwardly and rearward and thereby actuate inay' be also operatei'lv the universal bar to trip the escapenient and i permit letterspacing.

In the construction of the machiiieshown and describedfthe' ii'iaiii frame` comprises substantially two parts adapted to more relativcly to each other and' horizontally. The platen carriage and its associated parts together with the iinivci'sulbar is mounted .upon one of said frame parts and the typo action as well the means for operating the universal bar for spacing' piu-poses are mounted upon the other of the iiia'iu frame parts. There is a eomph-tebreak hetweeii the associated parts of the platen carriageandl the type actionfandv the construction issuch that the platen carriage with the associate .parts may be moved forwardlyw so as to be spaced substantially over the typebai's and in a compact and inoperativeI posia l H tion. x

Figs. 5 to 7 show a construction somewhat, similar to that shown in Figs. 1 to 4, except that the parts are arranged midcoiistructcd 4jaar a platen shift instead of a typeseg- A mciit shift.

In this `form machine thc base or `frame part 78 of the: main frame comprises side platcs, a forwardtpla't'eior- `bar 80 and `afrear plate oi' bar 81. The

upper portion of the member 78 is cut away and vertically movable thereon is'a `frame .y

. an inwardlY 30, a

partv 82. The main frame part 8*) comprises parts `83 and 81 which are relatively movable with iespect to each other and with respect to the base Q'Lniain frame part. 78, the. sides of the part' 61. being connected together by the carriage bed 81. The part 81 at each side of the machine has a downwardly extending portion 85 and connected to said portion 85 at cach side of the machine are parallel arranged arms 86 and 87. The arms SG atY opposite sides of the niachine are 'pivotcd to the side plates 79'on the base member and the arms 87 are held to a' transversel extending shaft 88. One of the arms 87 ias an upwardly extending arm 89 forming a bell-crank and at the up- )er end thereof is provided with a roll 90.

he roll 90 is adapted to enter slots 91 and 92'of shift levers .93 and 94 respectively. The shift leversl 93 and 94 at their outer ends are provided with keys 95 and are held in their normal position by means ot' Asprings 96 one end of each of which springs is held to one of the baseside plates 79 and the other end to an extension, as 97, on each ot' said levers. The shift levers are arranged in close relation on one` side of the machine and at the rear ends are pivoted at 98 to extendin portion 98 on the base side p te 79. Tie slots 91 and 92 of the shift levers are substantially L-shaped in form andthe upper or roll actuating portion 91 is inclined to a less extent than the `same portion of the slot 92`so that on the depression of the lever 93 the roll 90 will be moved to a lessextent than on the actuation of the lever 94. The substantially horizontal portion of each of the slots 91 and 92 is for the purpose of permitting the shift levers to be moved independently and if it were not for such horizontal portion of the slots the roll could not. move forward and in that case the frame part 84 could not be raised. The part B4 is supported by the arms 86 and 87 in substantially the samemanner as the ty e-bar segment of the other yfigures, but in t is case the normal position of the support 84 is that shown in Fig. y

7 and the two case shift movements are upwardly instead of one shift movement being upwardly andthe other downwardly as in he case with the construction shown in Figs. to 4.

L The yframe part 83 is slidably held to move horizontally on off-set portions 99 and such off-set portions are in alincment with ott-set parts 100`of the side plates 79 of the main frame part 78. Each otiset part .99 is slotted, and passing throu rli each slot. 101 is 'a stein of a screw 102. is provided with a milled or other head 103 by which the screw may be rotated and said screws 103 of opposite sides of the machine are adapted to old the members 83 and 84 v 05 in either. the knormal operative position ach screw 102 f vmounted a platen carriage 104 and in this carriage is a platen 105 about which thel work sheet ma;` be passed as usual.

'llie type action, except that the ,type-bars 80 are not sii-fted is substantially the'same asv that already described and the associated parts for the' platen are also similarly constructed, the main difference bein that the main frame has two parts, one o which is itself divided in two, parts to adapt the platen to be elevated for case shift purposes It will be understood that my iriventon is not limited to a carriage supporting.lr frame part havine a purely horizontal movement, as it will be obvious that the giuidingir means for said frame part 'may be inclined. if desired, in order that the carriage and associated parts may have adownward and forward movement while. upright instead of a strictly'horizontal movement. v

llaving thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a typewriting machine, the combi-v nation of a base frame part. an upwardly movable frame part supported on the base' frame part, a platen carriage movable from a normal operative position at the rear of the base frame part to a more compact inoperative position above the base frame part, a movable support for the platen carriage, connections ietween said carriage support and Said 'upwardly movable frame part whereby said support may be moved forwardly and rearwardly while upright to move the. carriage to and from compact position, a. kev action, type bars. and case shift mechanism. for actuating said -upwardly movable frame part to impart a case shift movement to the platen carriage.
